Insulated aluminum melting furnace

Abstract

The invention relates to an insulated aluminum melting furnace which mainly comprises a burner, a furnace body, a discharge end, a heat retainer and a smoke outlet, wherein the burner and the discharge end are respectively arranged at a burning zone in the upper part of the furnace body and a discharge zone in the lower part of the furnace body; the exterior of the furnace body is wrapped with a sealed smoke exhaust interlayer; the lower end of the peripheral wall of the smoke exhaust interlayer is provided with a smoke exhaust pipe; the smoke outlet is communicated with the smoke exhaust interlayer; the smoke exhaust pipe is connected with the heat retainer; the exterior of the smoke exhaust interlayer is further wrapped with a vacuum shell; a reflecting cover is adhered to the inner wall of the vacuum shell; the inner wall of the vacuum shell and the peripheral wall of the smoke exhaust interlayer are vacuumizing zones. The insulated aluminum melting furnace is capable of effectively ensuring the temperature of the furnace body and obviously improving the thermal efficiency of aluminum melting furnace, and furthermore is relatively low in cost.

Description

technical field [0001] The invention relates to an aluminum melting equipment, in particular to an aluminum melting furnace. Background technique [0002] Aluminum melting furnace is a commonly used equipment in industrial aluminum smelting. Excessive exhaust gas temperature has always been one of the main reasons for the low thermal efficiency of early aluminum melting furnaces; nowadays, the more commonly used aluminum melting furnaces are regenerative aluminum melting furnaces. The aluminum melting furnace recovers and stores the heat in the exhaust pipe and uses it for preheating the aluminum material, which greatly improves the thermal efficiency of the aluminum melting furnace; the regenerative aluminum melting furnace effectively solves the problem of excessive flue gas temperature, but affects the aluminum melting furnace Another main factor of thermal efficiency is the heat dissipation loss of the furnace wall. In traditional equipment, the heat exchange between the...

[0002] Aluminum melting furnace is a commonly used equipment in industrial aluminum smelting. Excessive exhaust gas temperature has always been one of the main reasons for the low thermal efficiency of early aluminum melting furnaces; nowadays, the more commonly used aluminum melting furnaces are regenerative aluminum melting furnaces. The aluminum melting furnace recovers and stores the heat in the exhaust pipe and uses it for preheating the aluminum material, which greatly improves the thermal efficiency of the aluminum melting furnace; the regenerative aluminum melting furnace effectively solves the problem of excessive flue gas temperature, but affects the aluminum melting furnace Another main factor of thermal efficiency is the heat dissipation loss of the furnace wall. In traditional equipment, the heat exchange between the furnace body and the surrounding air and its own heat radiation consume a lot of energy, which makes the thermal efficiency of the furnace body low. This aspect has always been It cannot be solved well; the traditional method is to use materials with low thermal conductivity for multi-layer insulation treatment, but the price is relatively expensive, and it has been unable to find a balance between price and insulation performance
